The operating system FreeBSD 9.0 has been released yesterday. The new version introduces several new technologies, feature additions and updates, including USB 3.0 support, the TRIM command for the Fast File System which improves interaction with Solid State Drives (SSDs), an update to Storage Pool Allocator version 28 which adds support for data deduplication and triple parity RAIDZ, and support for the Highly Available Storage (HAST) framework which offers network based Raid 1 functionality for additional data redundancy.
Additional features include updates to Gnome version 2.32.1 and KDE version 4.7.3, support for high performance SSH, an update to the NFS subsystem which now supports NFSv4 in addition to version 3 and 2, and kernel support for Capsicum Capability Mode, "an experimental set of features for sandboxing support".
Support for USB 3.0 and Fast File System TRIM support are without doubt two of the most important feature additions in FreeBSD 9.0. The USB subsystem furthermore supports USB packet filtering now, which can be used to capture packets which go through the USB host controller.
FreeBSD 9.0 is the first update of the operating system after the February 2011 FreeBSD 8.2 release, and the first major version update in two years.
Users who never came into contact with FreeBSD or another BSD variant before should start at the Resources for Newbies that offers help in selecting the right FreeBSD version, installation instructions and tutorials that should get most people started after installation.
FreeBSD 9.0 can be downloaded from the official website. The operating system can be downloaded as an ISO image which needs to be burned to DVD first, before the computer can be booted from it to start the installation of the operating system.
Additional information are available at the official website.
